Fix asset compression to check name ends with arg

There exists a discrepancy between how aapt1 and aapt2 prevent the
compression of assets using the -0 flag. aapt1 checked if the file name
ended with an argument, but aapt2 is checking if the file extension
exactly matches the argument. This change makes aapt2 behave the same as
aapt1 for asset compression using the -0 flag.
